To estimate the price of the 2023 BMW X6 M-kit V6 4.4L, I first considered the selling prices of similar cars. A 2021 BMW X6 xDrive 40i M Kit with a 3.0L engine sold for 250,000 SAR in good condition, and a 2022 BMW X6 V6 3.0L sold for 200,000 SAR, also in good condition. The target car is a 2023 model with a larger 4.4L engine, which typically commands a higher price. Next, I looked at the new car price for a 2025 BMW X6 xDrive40i M Sport, which starts at 453,125 SAR. Applying depreciation, a 2023 model would be approximately 15% less, around 385,156 SAR. I also reviewed listed prices: a 2023 BMW X6 M Sport with a 3.0L engine was listed for 373,000 SAR, and a 2023 model with a 4.4L engine was listed for 399,000 SAR. Considering the target car's average condition, I adjusted the estimate slightly lower than the higher listed prices but above the selling prices of older models with smaller engines.
